5 Physical Details That Reveal Highly Personal Information

As we mentioned here, with just a pair of eyeballs, a ruler and a negligent sense of propriety or fear, you can learn a whole mess of intimate details about any person at any given time. But why stop there? Here are five more shockingly personal things you can guess about anyone just by looking at them.

None of these are 100 percent, and you should not use any of them to make unfair assumptions about people. It is only in the name of entertainment that we point out that researchers have found ...

#5. You Can Tell How Honest Someone Is by Their Cheekbones (Sometimes)

Let's say you've never seen Star Wars. If you saw a picture of this guy, without knowing any of the context, would you say he's a good guy, or a bad guy?

Clearly he has villain written all over his face. But why?

Likewise, in real life sometimes you meet people that you immediately distrust -- something about their faces just makes them look like shady characters. Maybe it's the way he's standing in a dark alley, bedecked in a trench coat with the collar pulled up while pointing a gun at your skull. Or it could just be something about his face you don't like.

It turns out scientists have figured out what that "something" is.

How? Tell Me!

The cheekbones. While male models with chiseled faces might be effective in selling you underwear, in real life guys with wide cheekbones strike people as untrustworthy. And apparently there's a reason: Research shows that on average they're actually less honest. According to experiments, anyway.

Scientists at the University of St. Andrews in Scotland did a study and found that men with wider cheekbones not only cheated more at the game they were assigned to play, but also that when they screwed their fellow players over, those players were more likely to expect it. All they needed was a look at their faces.

The researchers think it may be because wider cheekbones don't form until puberty and are an indication of how big a man is going to get. Larger men tend to be more aggressive and are less likely to feel like they have to obey society's rules -- it's easier to screw somebody over when you know you can kick his ass if he complains. Even in jobs where aggressiveness is rewarded, like professional sports, researchers found that, "broad-faced ... players spend more time in the penalty box."

Those researchers did not point out that Darth Vader was designed to have exaggerated cheekbones, but seriously, check it out:

And is it any wonder Christopher Lee made his career playing villains?

His next role? Governor of Texas.

Please keep in mind, the statistical difference is slight, and this is useful only for understanding why we feel weird about people with that face shape. Please don't immediately stab the next dude you see with wide cheekbones, or assume he's always lying. That probably makes you the bad guy.

#4. Want to Know How Much Sex a Guy Is Having? Look at His Baby Pictures

If '80s teen sex romp comedies have taught us anything, it's that losing your virginity is just about as important as whether or not you're alive at all. Statistically speaking, there's actually a pretty solid way to know if a guy is going to be a junior man slut or the 40-year-old virgin.

How? Tell Me!

By finding out how fat he was as a baby.

Scientists at Northwestern University in Illinois studied 770 men from birth until they were 22 years old. From that, they found that infants who gained weight the fastest had sex earlier, got laid more often and reported higher numbers of sex partners. Also, they were more athletic later in life.

The reason, according to the researchers, might have to do with something called the hypothalamic-pituitary-gonadal axis, a triumvirate of glands that control a buttload of stuff, including sex hormone production. The same surge in weight gain that makes fatter babies between birth and 6 months of age also predicted a similar surge in sexual hormones years later, one that hits before their skinny baby buddies get theirs.

By hitting sexual maturity earlier, they get a big fat head start on the sex game, and if the numbers are any indication of anything, they're taking advantage of that early bird special.

#3. If He Has a Bigger Penis, He Is More Likely to Be Gay

We have previously mentioned that finger length ratio and the direction of a person's hair swirl were good indicators of whether someone was more likely to be gay. The problem with those measurements is that they're pretty hard to get without posing as a manicurist-slash-barber. Plus, if you're getting that intimate with another man's fingers and scalp, you're probably already pretty certain of which way the pendulum swings.

The good news is that we've got another measurement that's a little easier to spot from distance, and is, statistically speaking, a decent indication of sexuality. The bad news is that, well, you'll see.

How? Tell Me!

It's dick size. Gay men usually have bigger dicks. So, this is probably one you'll have to try in the locker room.

That's right, guys. Length, circumference, the whole sha-wang. When erect, a gay man's penis is an average of 1/3 of an inch longer than a straight guy's. It's also chubbier. Perhaps even more interestingly, massive gay junk seems to be skewing the overall average penis length up to 6 inches, while the average straight man's is actually just a fraction shorter than that.

The only thing is, no one was actually taking a tape measure to the test subjects' boners (they were measuring themselves), so we don't know if the numbers were 100 percent accurate. But current researchers say that there is no reason to believe gay guys would exaggerate their numbers more than straight guys. So while the numbers might be inflated overall, the discrepancy is almost certainly still legitimate.
